Re: [CentOS] Best way to duplicate a live Centos 5 server?

The problem is I need to minimize downtime so was trying to figure out a way to live clone the original. Initially, I thought I could do this via exporting an iSCSI target from the virtual host, create a MD raid 1 array on the C5 server, wait for it to sync, then shutdown the physical server and switch to the virtual one. But after getting iSCSI working... I realize I could not create a md device on a mounted disk. Unfortunately this old C5 wasn't setup with md raid 1 originally so I can't just add a the iSCSI target as an additional member for a triplicate. So I remembered DRBD was supposed to be used for replication. But after getting things set up, running the drbd-admin create-md command gave me this scary warning it will destroy data on the disk. Apparently because drbd writes meta data to the drive. So that appears to be a no go too. Am I missing something glaringly obvious here, or is the only way I'm going be able to migrate is to shutdown the C5 server for a few hours while duping the old drives? Would greatly appreciate any pointers how best to do this. You could always rsync the old server to the new one... a few runs will get 99% of the files, and a quick run after the shutdown can get the rest...

These situations need different grub configs. I generally configure both drives as if they were hd0/sda. That way, if sda crashes, I can remove the disk and boot the second drive normally.

Re: [CentOS] One disk speed problem [SOLVED], and a question on hdparm
on 3/26/2012 1:49 PM m.r...@5-cent.us spake the following: I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran across something: partition alignment. A thread where someone who'd done some tests and found that was his problem. So, here's the answer: we have these Caviar Green 2tb drives (the thread I found had either a 1tb, or 1.5tb), (and no, we are *NOT* going to buy Caviar Green for servers ever again). The big thing is that they use 4k sectors, *not* 512 bytes. Following directions, I pulled it into fdisk, and then used a command I've not needed before: u. This changes units from cylinders (the default) to sectors. Having done that, p shows that it actually starts in sector 63. Again, following directions, I changed it to start in sector 64. Finished the partition, wrote it, made the filesystem, and tried it out. 177G transferred in 1h 47+m. So, anyone who's got new drives that use 4k sectors should probably follow this. This also probably explains parted's completely aggravating complaint that the partition's not aligned, but gives you no idea *why*, or how to align it - I pulled the drive into parted, and told it to print, and it did *not* complain the partition wasn't aligned. Next trick: hdparm. I want to disable, or at least shove way up, the spindown timeout on these drives, which, depending on the thread you read, is 6 or 8 seconds. hdparm should let me do that... but before I do, I'd like to know what it's set at. Does anyone know how to find that out? And no, the manpage is wrong, hdparm -Bno parm) /dev/sdx does *not* read it, it just complains it's missing the parm. mark Isn't it sdparm for scsi and scsi emulations? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I changed mailservers this weekend, going from a Centos 3 box to a Centos 6 box. The Centos 3 box used the old standard imap and pop servers. We use horde for our webmail. The pop3 mailboxes (mbox) were in /var/spool/mail and the imap folders were in /home/user/mail, which horde took care of. So 2 classes of users? As John has annotated, mixing POP3 and IMP4 use is not advised at all. Not really two classes of users. Most of the users use pop for retrieving email. Horde is our webmail app, and it reads the mailbox, but creates and manages the imap folders in user's home directory. This has worked fine in the past, allowing users to read mail from their desktop using pop, and if desired, using horde to read mail from elsewhere. If they want to be able to see read email from outside the building, they set their mail client to leave on server. Horde takes care of deleting email from the mbox as well if desired. Upon starting the Centos 6 box, I ran into tons of login and viewing problems. I tried Cyrus for imap, could log in, but couldn't see mail in the imap folders. Using dovecot for pop, I eventually could get logged in, but kept getting the couldn't open INBOX message, so no one could download their email, even though sendmail was delivering it properly. Cyrus-IMAPd is out of the game unless you do a real mail store migration as Cyrus-IMAPd uses his own storage scheme. My preference is to use dovecot as both pop and imap servers. The Centos 3 imap server used an rpm named imap-2002d-12 (at least that's the one I have on that server). I'm not sure how mixing comes into play here, since most people set their smart phones up as imap clients, and they can still view their email when they arrive at work using pop. So here's my question: Can (should) dovecot be used for both imap and pop when considering the above setup of mbox in /var/spool/mail and imap folders in ~/mail? Horde will read the mbox to display new messages in it's screens. Yes. That's good to get an opinion. I'm going to proceed thinking dovecot will do both. There's also an issue to address later of shared stuff I'll have to investigate. We have a few accounts that multiple users use in this manner through imap. They log in as a singular user, but there are issues of deletions and the like that sometimes cause problems. If so, does anyone have a pretty good link to how to make dovecot function using the old Centos pop/imap scheme? Should I try and convert the old mbox files to another format or destination to make this work? See http://wiki.dovecot.org/MailLocation I reviewed that quite a bit during the night. I guess I need to read up on dovecot's definitions, since that INBOX parameter kept throwing me. There really isn't an INBOX to a pop account's mbox, but there is on our imap scheme. So I might have been trying to force the issue. Thanks for any help. It's been a long night, going on about 14 hours now and I'm just getting the old server back to current until I figure this out. Not intended to sound smart ass, but changing a production system the way you do without prior testing isn't that clever. Not taken in any bad way. I had actually tested it pretty well for all the stuff I'm running on it. Sendmail worked as expected. All of the other apps I have running dealing with email worked fine as well. Apps such as MimeDefang, MailScanner, MailWatch, and everything else. I took for granted that pop and imap would work fine since on the old system, they just worked. I had no idea these services had changed so much. So yes, I failed to test the two things that users want most. Egg on my face, for sure. Thanks for the help, and criticism. steve campbell I wish you success. Thanks. Steve, I know I'm late to the party, but you are saying your old server was running UWimap ( by the statement of imap-2002d-12)?

So, all shares are mounted at /mnt/s1, and the contents of the multiple data dirs appears in one single data dir? The only time I've seen such functionality is within the XBMC media center application. It allows you to mount multiple network shares, but shows them all in one location as a sort of 'overlay' view. Duplicate directories are shown have their contents merged, but remain intact on the actual shares/filesystem. Does any of this make sense? Is it possible with CentOS (pref. 6) ? If nothing else, you could create ans script that would create symlinks from all files in those directories into single one. I use that technique to create combined repository directory for mrepo.

Re: [CentOS] setting up bare minimal CentOS VM
snip Craig, yes, and no. I am actually looking for a list of software packages that can be removed without breaking the running OS. like for example bluez-libs or cronie-anacron which isn't necessarily needed for a bare-minimum system to run. I honestly don't just want to delete stuff that I don't know if it could break something, so I was hoping maybe someone knows of a list (on a wiki / blog / etc) that has a really bare minimum list of software that needs to be on a server to function. I could install anything else later on if I need to though. I really think the minimal CD would be about as lean as you would want to go.

Re: [CentOS] Initial 6.0 trees in QA
on 5/26/2011 11:50 AM Steven Crothers spake the following: snip Fedora and Debian in my opinion are both superior to the way CentOS opens community development. Having one developer doing all the packaging (Johnny) is a waste of resources and intelligence. A simple repository where we can all contribute to the build cycle would be far more beneficial in the long run for the project. However, they are currently worried about people stealing their work and starting their own rebuilds of RHEL, which if that was going to happen it would have already. The SL team opens their build process and we can get close enough with Fedora to make a good start. Some of the developer paranoia needs to go, and more community involvement needs to happen still. However the QA system is a good step forward and like I said, hopefully the first of many over the next few years. I think they are as much worried about bad things getting introduced into an uncontrolled build environment. Things like dependencies outside the normal build, dependencies that break other parts of the distro, and even general malicious content are all concerns of a full enterprise type of distro. CentOS is not a community build... The community is in the support. I think opening up some of the problems in building so maybe patches can be submitted is a good step, but if I wanted a distro that anybody and his brother can add to, I would USE Fedora... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] centos friends?
on 5/5/2011 1:55 PM Dave Stevens spake the following: Hello All, I want to ask about CentOS and money. Please do not start some kind of shitstorm over this, it isn't productive. I have just been looking at archive.org to see when the paypal option went missing from the donate menu at centos.org. I can't pin it down, but it was there on October 16, 2010 and isn't now, so that's the information I have on that point. There was a great deal of argy-bargy on this list when the 5.6 update was slow arriving. I don't want to go there, I was happy to see it when it arrived, as I always am when there's an update. The impression I got was that the maintainers and packagers were working as hard as they could and were tetchy about being nagged, being unable to do more. Fair enough, but we need not adopt the status quo entirely. The donate menu on the web site has this to say, (and more) ... The CentOS team would like to remind you that the primary means of substaining the development of CentOS is via contributions by CentOS users. CentOS is now, and will continue to be totally free; however, it takes money and resources to make CentOS available. If you are able, please consider donating to the CentOS Project. Donations of promo material, public mirrors and dedicated servers are all vital to our contined operations. Monetary CentOS is currently reviewing our cash donation program. In the mean time we are not accepting any financial donations. We do appreciate though, if you want to - for example - help out with promo material. See our Wiki page on donations for more up to date information. So referring as directed to the wiki page shows: Resource and financial needs The CentOS Project is entirely based on the efforts of volunteers. We rely on contributions and donations from CentOS users as well, for: * Logistics related to promotion and infrastructure * Specific hardware needs * Bandwidth and connectivity * Promotion material at conferences and exhibitions * Organizing CentOS-related events I don't see anything there about money except in the first line and I'm really curious why. Internally it is clear that if the team hasn't put in place some cash donation basis probably the capacity isn't there. But the current team need not go into areas where they have no time or (perhaps) expertise. There are lots of capable money folks in the free software world who can and do accept donations and deal with administrative infrastructure and channel support to projects. So the name apache-friends is suggestive. Without necessarily using that model I wonder why there isn't a CentOS Friends group or fund to which I and others can donate. I can't help but believe that if there were, say, a couple of paid staff with CentOS as the day job, things would not be so burdensome to the devs we have now and maybe we could build on that. For my part, I installed CentOS on some machines I administer for non-profit groups in Canada. The lack of licencing fees makes a big difference to them, non-profits groups are perpetuually long on brains and short on cash. But even so I think we could cough up, say, ten bucks a year per machine to put some payback into CentOS. Given general widespread goodwill this might be multiplied significantly. I have not seen this discussed on the list and would be happy to know if there is some reason it hasn't been attempted. Please let me repeat, this is meant as a constructive suggestion, there is no problem with the product, quite the reverse. Comments?

Thanks for correcting me. Couple of questions, then What is the average current time commitment per week, i.e. man hours that is currently volunteered by the core developers? What would that need to increase to, to significantly reduce release times (which I think was the overall goal)? What would the *market rate* be for the skills required? Just to give a rough figure to work with and shouldn't be related to any particular person's current day job. Thanks in advance, Ian. A good linux sysadmin in the US makes from 60K to 80K USD a year... High level programmers a bit more... So with benefits, and other support costs... How about a half million to three quarters of a million a year to commercialize CentOS... In US dollars... Get your checkbook out... Anyone know someone who can front at least 2 years working capital to get started and productive? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Server locking up everyday around 3:30 AM
snip (those commands should run the cron normally except starting at 03:00, where it should kick off at 3:15 instead of 03:05) If it also fails to start at 03:15 then that would suggest that something is happening to the cron job the last time it is run to make it hang (or make the system think it is hung). I wonder if the other end has some file(s) locked for writing or other reason and that is choking the local wget. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This is one of those so I'm doing this very gingerly to avoide losing the DB on the raw disk If you are going with CentOS 3, you might as well go ahead and get 3.9. 3.5 + security updates = 3.9 And I would image all the raw drives before doing anything if you are not sure...

Re: [CentOS] Any update on 5.6 / 6?

Stevens spake the following: 2011/2/14 robert mena robert.m...@gmail.com: Hi, Despite the mailing list and twitter I did not find any updated info on either versions regarding the current status. So, what is the current status of both versions? (like 60%) I wonder for a long time why there is no detailed information about the release status. For example: 1) Upstream 5.6 release 2) rebuilding packages (2-3 days) 3) CentOS patches (1-7 days) 4) QA (2-3 weeks) 5) distribution on the mirrors (3-4 days) 6) CentOS 5.6 Release A small roadmap would certainly help many users. Best regards, Morten I suppose the CentOS devs have other minor duties like feeding families, taking children to ball games and dance recitals, helping with homework, etc... The dev staff is not large, and any time spent answering is it done yet queries will slow them down further. I never ask, and never complain, since I don't feel this totally free product owes me anything...

Re: [CentOS] centos 5.5 check memoray usage too high???
on 2/2/2011 1:58 PM mcclnx mcc spake the following: We have DELL R900 server with 128GB RAM (CENTOS 5.5)in it. This server only have one application running and few people use it. Every week I ata least get one or two messages from monitor tool mail to me say: Message=Memory Utilization is 92.02%, crossed warning (80) or critical (90) threshold. Since server have 128 GB RAM and only 1 application. I really don't belive that. Does there has some way can check memory utilitation ? Thanks. Linux has a habit of using memory to store buffers and speed disk re-accesses. As soon as an application needs that memory, it will be flushed if dirty and released. Memory unused is memory not needed. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Well, some will wait, or be busy hounding about CentOS 5.6--isn't there an upgrade in 4.x too? :) Not knowing how much preparation the development team has done, I'd expect it to be longer than usual---there are some major changes. However, I suspect we're all looking foward to it. (Save those tasked with immediately implementing it in production as soon as it's released.) Last time there was only one build queue, so if 5.6 and 6 come out at the same time, they will have to choose which one gets attention first. CentOS doesn't have the multi-million dollar infrastructure to support multiple simultaneous releases. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
